7 Be it known that I, AXEL A. Srnon, a citizen of the United States,residing at Austin, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Acetylene-Gas Apparatus, ofwhich the fol-- lene-gas apparatus provided with my im prove;- ments;Fig. 2, a section taken at theline 2 2 on Fig. l and viewed inthedirectionof the arrows; Fig. 3, a section taken at the line 3 3 on Fig.1 and viewed in the direction of the arrows, and Fig. 4 a section takenat the line 4 4 on Fig. 1 and viewed in the direction of the arrows.

A is the gasometer, comprising the lower stationary tank A and theinverted tank or bell A telescoping therewith, and carrying acentrally-pendent pipe at, telescopingwith a pipe 1), extending upwardfrom the base of the tank A, near which it communicates through a branchpipe I) with the outer air 1' or the escape of excessive gas-pressure inthe gasometer. In the base of the tank A is formed a water-holder G,having an overflowspo'ut 61 outside the tank. A gas-outlet pipe 6,supported on the top of and opening at its lower end into thewater-holder, rises above the water -line 7m in the gasometer and has abranchc' leadingto the point or points of gas consumption, burners. (Notshown.)

C isan extension of the holder 0, shown as a pipe, which maybe of anydesired length, leading outward from the holder, with which it has opencommunication to receive water from the supply therein, (indicated at w.The water contained in the pipe or conduit 0 and which is suppliedtheretofrom the holder 0 renders it a check against backflow when thecarbid-holders are disconnected, as foremp tying them of gas from thegas-holder A into the room containing the carbid-holders.

D D are carbid-holders or generators proper of any desired constructionand provided in any required number placed at intervals along eachside'of the'exten'sion G and each communicating therewith through agas-outlet branch pipe f. Above the check-pipe O and communicatingtherewith through tubu lar legs g provided at intervals, is supportedthe pipe g for conducting the gas as it is generated fromthecarbid-holders to the-gasometer through the vertical pipe 9, Iextendingtherein, upwardfrom the' holder 0 beyond the water-line so. The pipeO-,-leg s g and pipe g aiford, practically, a singlegas-check conduitcommunicating at its base portion with the holderGand from its upperportion with the pipe g, and it is within my invention toprovide asingle conduit of suitable form to receive the water-supply from theholder and conduct the gas from the CflIblCbhOldQl into the gasometerinstead of the two intercornmunicating pipes G and g. According to theconstruction illustrated the supply of water for the carbid-holders istaken from the water in the gasometer A through a pipe 71., into whichthe water is admitted by way of a valve-controlled chamber (indicatedatE) 0f anysuitable construction, but which forms-no part of my presentinvention, being described and claimed in my pending application, SerialNo. 699,439, filed December 16, 1898, so that it need not be shown nordescribed in detail in the present connection. It is sufiicient tosaythat the stem 11 of the valve in the deViceE is in alinement with anactuating-rod i, supported on the bell A whereby when the bell drops farenough under reduction of pressure in the gasometer the rod encountersand depresses the valve-stem i to open the valve and admit water intothe chamber from the gasometer throughthe communication 7? therewith.Any other suitable means for supplying water, to the carbid-holdersthrough a pipe- 11 may, however, be. employed without departure frommyinvention. The pipe h has branches 7t, each terminating in a header ormanifold branch 7L2 for each of the series of carbidholders D atopposite sides of the plane of the pipe 0, and from each branch it therelead at intervals into the carbid-holders tubes h one for each holder,and'which may contain shut-off valves 71 By the construction thusdescribed when by the drop of the bell A the valve in the device E isopened to admit water from the gasometer into the pipe h the volume ofwater composing the charge is conducted throughout the manifold pipes 7Lwhence it is distributed through the tubes 71. to the carbidholders,with the advantage that it is supplied to them all uniformly andsimultaneously, thereby causing them to operate accordingly. The gasevolved in the carbid-holders passes through the water in the check-pipeC, supplied from the holder 0, into the gasometer by way of the legs gbranch g, and pipe g.

To prevent escape into the inclosure or room containing the apparatus ofthe condensation which finds its way into the holder 0 through the pipesg and e, the spout d, from which the odor would thus escape, is closed,as by a cover 01, and has a nipple d leading from it at a point adjacentto the normal water-line in the spout into an angle-coupa ling ddischarging into a tightly-closed box 1* through its top. This boxaifords aspecies of trap or catch-basin for the condensation and may beremoved from time to time, as required, to the outer air and uncoveredto clean and purify it.

My improved safety-escape device for excessive gas-pressure may be usedto advantage with any gas apparatus involving a gas ometer having a tankA and bell A As shown in Fig. 3, this device involves the following-described construction: The top of the escape-pipe b is providedwith a seat Z for a valve Z, normally held against its seat by aspringvl confined about the valve-stem Z extending downward into thepipe. 011 the upper end of the valve-head is fastened a crossbar Z theends of which form lateral projections engaging with opposite verticalslots m in the pipe at, of a length so proportioned that when thepressure of gas in the bell exceeds the predetermined pressure theconsequent rise of the bell brings thelower ends of the slots intoengagement with the projecting ends of the cross-bar Z and the continuedrise of the bell lifts the valve to open the pipe I) through the slots mto the gas-pressure and permit escape thereof to the outer air until bythe resultant fall of the bell the lower ends of the slots aredisengaged from the valve, which is thereupon closed by the action ofthe spring to seal the pipe 1) against the further escape of gas untilthere shall be again excessive gaspressure in the gasometer. I

An incidental but very material advantage of the valve structure ofsafety-escapes is that it avoids the necessity of providing on the upperend of the pipeb a stop to be engaged by an inward-projecting stop onthe lower end of the pipe a, and thereby prevent undue rise of the bell.The provision of these stops not only adds materially to the cost ofmanufacture, but the only guide the pipe at has on the pipe bis at thesestops. By omitting the stops the pipe or may so closely fit the pipe I)as to afford to the movable pipe an extended guide in rising andfalling. Since the valve Z encounters the lower ends of the slots 'm assoon as there is excessive pressure in the bell, the further risethereof is rendered impossible, and the stops thus become unnecessary.

What I claim as new, and desire to secure by Letters Patent, is-

1. In an acetylene-gas apparatus, the com-.

bination with a gasometer of a separate water-holder formed in the baseof the stationary tank, a gas-pipe extending upward in the gasometerfrom and communicating with said water-holder, a gas-check conduitconnected with and receiving its water-supply from said holder andcommunicating with said pipe, and a carbid-holder communicating withsaid conduit.
